摘要

摘要: 研究拱脚水平方向弹性支承拱的屈曲，提供弹性支承拱在3种荷载下的线性分析结果，分析拱的对称屈曲和反对称屈曲，得到对称屈曲和反对称屈曲的分界。最后提出临界轴力的计算公式及设计建议。

Abstract: It was studied the bucklings of horizontally elastically supported arches, and the linear analytic results of the horizontally elastically-supported arches under three loads were also presented.The symmetrical and antisym-metrical bucklings of such arches were analyzed, and a demarcation between the symmetrical buckling and antisymmetrical one was got.The formula for calculating the critical axial force as well as the recommendations on design were put forward.
